COMBINATION-LOCK FOR MONEY-DRAWERS, 86C.

SPECIFICATION forming part of Letters Patent No. 338,205, dated IvIareh16, 1886.

Application filed May 16, 1885.

To all whom it may concern:

Be it known that I, HERBERT M. SrURGIs, of Hillsborough, in the countyof Hill and State of Texas, have invented a certain new usefulImprovement in Combination Locks for Money-Drawers, 850., of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, and inwhich- Figure 1 is a perspective View of the inside of the drawer,showing my improved lock applied. Fig. 2 is a similar view of the bottomof the drawer. Fig. 3 is an enlarged detail section taken on line 3 3,Fig. 1, showing the drawer unlocked, so it can be pulled out. Fig. 4 isa similar view showing the drawer locked in place. Fig. 5 is an enlargedtop view of the part of the lock shown in Fig. 1, the top of the housingbeing removed. Fig. 6 is a section taken on line 6 6, Fig. 5. Fig. 7 isa section taken on line 7 7, Fig. 5; and Fig. 8 is a section taken online 8 8, Fig. 7.

My invention relates to a combination-lock for money-drawers, 850., forstore use; and my invention consists in features of novelty hereinafterfully described, and pointed out in the claims. V

Referring to the drawings, A represents a money-drawer, and B part of astore-counter or other support, to which the drawer is secured in such amanner as to be moved in and out to open and close it. Secured to theinner part of the drawer is the housing Oof the lock. Vithin the housingis pivoted a frame, 0, by a rod or pin, 0 the lower end of which isheld, when in its normal position, toward the inner end of the drawer bya spiral spring or springs, 0. (See Figs. 4 and 8.) The frame has a toprod or round, 0, and a bottom bar or strip, 0 to the former of which arehinged two or more bars, D, the connection preferably being made byslotting'the inner ends of the bars to receive the rod, and then passingpins D through them (the rods) back of the round, as shown. The barshave hooks D on their free ends, which may be made to project up ordown, as desired, by taking out the pins D and reversing the bars. Whenthe drawer is closed, these hooks enter between a lower jaw, I, andupper jaw, I, secured to the counter Serial No. 165,744). (Model.)

or other support of the drawer. \Vhen the hooks are turned down, orthose of them that are turned down, they engage the jaw I and preventthe drawer being pulled out until they are raised, which is accomplishedthrough means of vertical levers J, pivoted to the housing 0 by a rod,J, passing through horizontal extensions J There is a lever for eachbar, and to the lower end of each lever is connected a rod or wire, L,that extends to near the front end of the drawer, (see Fig. 2,) whereeach is provided with a finger-piece, L, guided and held to the bottomof the drawer by a bracket, L, through which they can move freely. Bypulling on any one of these wires the corresponding bar D will beraised. I

In practice part of the hooks of the bars would project downward andpart upward, and the corresponding wires of all those that projectdownward would have to be pulled at once to unlock the draw, as all thehooks will have to be raised from the jaw I before the drawer can bepulled out, and an unauthorized person would not know, without firstlearning the combination, which bars to raise.

To make the lock still more secure and effective, the jaw I is provided,so that every time a wrong bar is operated the hook of that bar will belifted and engaged with this jaw, so it will be seen that just the rightbar or bars, according to how many hooks are turned down, and no other,must be operated to unlock the drawer; and with a number of bars (I haveshown six) the lock is susceptible of a quantity of combinations, andall that is necessary to do to change the combination is (as beforestated) to reverse one or more of the bars by removing a pin or pins, D.

I have shown the jaws I 1 formed on a bracket, 1 (See Fig. 1.)

Thelevers have projections J 3 on their lower ends, that come againstthe bar C of the frame when the levers are pulled back, thus throwingthe bars D forward slightly as they are lifted by the levers, (see Fig.3,) to prevent friction against the lower jaw. WVhen the lower end ofthe frame is thus forced over by the operation of a lever or levers,itis restored,when the pressure is removed from the lever or levers, bythe spring or springs C above mentioned.

Then it is attempted to open the drawer and a wrong bar or bars raised,the upper end of the frame will be pulled toward the inner end of thedrawer by means of the hook of such wrong bar engaging with the jaw I.The consequence of this would be to force the lower end of the frametoward the front end of the drawer against the spring 0 and in doingthis a projection, N, on abar, N, hinged at N to the frame, comesagainst a projection, O, on the inner end of a hammer, O, pivoted at Oto the housing 0, and pulls the hammer back to the position shown indot-ted lines, Fig. 5, against the pressure of a spiral spring, 0 and assoon as the projection on the bar passes the projection on the hammer,thehammer is pulled back by the spring and strikes agong, P,'giving analarm without the drawer being unlocked. The hammer has anotherprojection, O, that supports the free end of the bar and keeps it fromfalling.

I have shown the lower ends of the levers J projecting from the bottomof the drawer through an opening, A, the wires L being connected to thelevers outside the drawer. The opening may be covered by a shield, U,open in front for the passage of the wires, as shown.

I claim as my invention- 1. The combination,with the drawer and itssupport, of a pair of jaws, a plurality of bars having hooks turned inopposite directions for engaging said jaws, and operating levers androds or wires for actuating said hookbars, as explained.

2. The combination,with the drawer and its support, of the pair of jawsI I, the pivoted rods D, each having a hook, D", projecting from oneside thereof, one or more of said hooks being presented toward each jaw,as explained, the finger-pieces L, and the connections between saidfinger pieces and hookbars, substantially as set forth.

8. In combination with the drawer and its support, the hinged reversiblehook-bars, pivoted levers for raising the bars, wires or rods foroperating the levers, and jaws I I, all arranged and operatingsubstantially as and for the purpose set forth.

4. In combination with the drawer and its support, the pivoted frame 0,reversible hookbars hinged to the frame, levers for raising the bars,wires or rods for operating the levers, jaws I I, bar N, pivoted to saidframe, springhammer having a projection engaged by a projection on thebar, and a gong, all arranged and operating substantially as and for thepurpose set forth.

5. In combination with the drawer and its support, the pivoted frame 0,having rod (3 and bar 0 hook-bars hinged to the frame, levers forraising the bars, projections J 3 on the levers, for engaging the bar vof the frame, spring or springs 0 wires or rods L, and jaw I, allarranged and operating substantially as and for the purpose set forth.

I 6. In combination with the drawer and its support, the'frame G, havingrod 0', reversible hinged hook-bars secured to the frame by beingslotted to receive the rods 0 and by pins D, pivoted levers for raisingthe bars, wires or rods for operating the levers, and jaws I I, allarranged and operating substantially as and for the purpose set forth.
